Re: TT/Mega STE power supply headaches

Could be yes.. I guess if voltage on the core was to high, Q2 would turn on and prevent C8 from charging... (which seems like the problem you are having).

Have you check -12 voltage ?

I can't remember there was a bug fix announced somewhere in EXXOS
Are you thinking of GB6 bug with TOS206 ? That was software fix.. not OS fix...

I've noticed that one chip on the left of the processor is missing on my board compared to other STe mainboards. Does anybody know, what is it good for?
Its the blitter... Its integrated in the large SMT chip to the left on later machines.

Re: TT/Mega STE power supply headaches

I'll do that later this evening and report... I'll also replace the cap just to be sure. I also ordered a set of replacement transistors for a pound so will replace all three when they arrive... I don't really get whats going on with Q2 anyway.. linked to the transformer winding directly, not even ...

Re: TT/Mega STE power supply headaches

So capacitor is not charging which is the problem... you 100% sure you have put in pcb correct way around ?

You could try removing Q2 and see if PG works then...

Re: TT/Mega STE power supply headaches

Do you get 5V and 12 V on one side of R29,R31,R33..

On collector of Q2, turn on and see if the voltage changes over time.. try over 60 seconds...
